A major constrain of MRI superconducting magnet design is the cost and it becomes increasingly important given the dynamics in global market. Shimming system, an essential subsystem in MRI magnets, is one of the areas where constant efforts have been put down to make it more cost-effective. In this paper, a novel magnet coil design scheme, which minimizes B0 inhomogeneity through micro-adjustments of main coil currents, is presented. This design could substantially reduce system cost in comparison to traditional designs such as a set of standalone shimming coils.
